SPECIFICATION formingpart of Letters Patent No. 240,764, dated April 26,1881.

Application filed March 11, 1881. (No model.)

To all whom it may concern: Be it known that I, DAVID M. REYNOLDS, ofOxford, in the county of Chester and State of Pennsylvania,'haveinvented an Improvement in SpringChimney-Holders for Lamps,

of which the following is a specification.

Lamps have been made with a circular range of vertical springs forreceiving and holding the chimney. These springs, being of metal, arenot reliable for holding the chimney, because the metal does not clingto the glass, and the chimney is liable to work or crawl upwardlybetween the chimney-springs when exposed to the jarring or shakingmotion incii5 dent to transportation from place to place by hand.

Lamps have been made with rubber upon the catch or at the end of thescrew, for holding the flanged chimney and preventing injury by unduepressure.

Myinvention relates to the combination, with the metal chimney-holdingsprings, of elastic material, such as india rubber, leather, or iibrousmaterial, that intervenes between the 2 5 metal and the glass, andyields to the glass, and is compressed sufficiently to produce theproper amount of adhesion between the elastic material and the glass tohold the chimney in its place upon the burner, and to prevent c thechimney moving upwardly when the lamp is agitated.

In the drawings, Figure l is an elevation of theburner with one of thechimney-springs in section. Fig. 2 is a separate view of one of 5 themetal springs; and Fig. 3 is a horizontal section at the line as m, thescale of the two latter figures being larger in size than Fig. l.

The base a, air-distributing plate b, wicktube 0, and cone or deflectord are to be of any usual character.

The glass chimney 0 is supported upon the rest that in this instance isthe outer edge of the air-distributer, and around this there age thechimney-springs f, made of metal, of the I proper size'and shape, andfastened at their lower ends below the chimney-rest. t i are thechimney-holders, of rubber or similar material,that intervene betweenthe metal springs and the glass. I prefer to use bands of such rubber,and to cut into the metal of the chimney-spring openings at 0 0 for theband to pass through; but where the band is endless I employ tongues 11.n, that are turned aside to allow the band to be slipped over them, andthen they are bent back to place in line with the rest of the metal ofthe spring, thereby holding the band in place.

It is to be understood that the glass of the chimney, coming intocontact with the rubber chimneyholders, compresses them slightly, andthat they cling to the glass, so as to keep the chimney in its place andprevent it work. ing oft, but allow of its easy removal or reinsertionbetween the spring chimney-holders.

I am aware that leather has been introduced between the edges of adome-supporting disk and the interior of the chimney. In this case Msuch leather is exposed to the heat thatis conducted from the metaldome. By my improvement the rubber or similar material applied to thechimney-springs that extend upwardly from the lower part of the burneris not injured by the heat, because the springs do not become heated.

I claim as my invention.

l. The combination, with the metal chimneyholding springs extendingupwardly from the body of the burner, of india-rubber or equivalentelastic material connected to the metal springs, and intervening betweensuch springs and the glass of the.chimney, substantially as and for thepurposes set forth.

2. The metal chimney-holding springs provided with openings 0 andtongues 01, in combination withthe bands ofrubber or similar materialpassing around the tongues and through the openings, substantially asset forth.

Signed by me this 22d day of February, A. D. 1881.
